How to connect Samsung Galaxy Watch 6 to iPhone

Galaxy Watch 6 doubled the peak brightness of its predecessor and introduced FDA-cleared AFib detection during sleep. Wear OS still requires Merge to work with an iPhone. Here's the complete setup.

Galaxy Watch 6 hit 2,000 nits of peak brightness - double the Watch 5 - which means the display is genuinely readable outdoors without adjusting your wrist. FDA-cleared Irregular Heart Rhythm Notifications run entirely on the watch with no phone required at the moment of detection. Two meaningful advances sharing one platform limitation: Wear OS offers no native iPhone support. Merge removes that limitation: pair Watch 6 to your iPhone for notifications, call management, and Apple Health syncing.

What you get through Merge

Through Merge, the Galaxy Watch 6 connects to your iPhone for notifications, calls, health sync, contacts, music control, and camera remote. Every notification from every app reaches your wrist in real time - Messages, WhatsApp, Mail, Slack, and anything else you enable. The 2,000-nit display means those notifications are readable outdoors at a glance, without any wrist repositioning or shading the screen. You choose which apps push alerts to the watch and which don't, and you can dismiss incoming notifications from the watch directly.

Incoming calls ring on the watch and can be answered and handled from your wrist - iPhone contacts sync to the watch so you know who's calling. Music on the iPhone is controllable from the watch: skip tracks, adjust volume, and pause without fishing out your phone. With the camera app open on iPhone, the watch becomes a remote shutter. AFib monitoring runs on-device regardless of which phone you use - that's entirely independent of Merge.

Health data syncs to Apple Health: heart rate, steps, distance, floors climbed, calories, and workouts with GPS routes and pace all transfer automatically after each session.

First-time setup

If setting up from iPhone, the Merge app includes a built-in wireless installer that activates the Watch 6 without any Android device involved - the complete setup path runs entirely through Merge on your iPhone. If you also have access to an Android phone, the Galaxy Wearable app is the preferred route: it handles Google account sign-in, Play Store configuration, and Watch 6 firmware updates in one guided flow before you hand the watch over to Merge.

Pairing Merge with Galaxy Watch 6

Keep your iPhone and watch within a couple of feet of each other throughout setup.

  1. On your iPhone, search the App Store for Merge Watch and install it.Download on the App Store
  2. On the watch, open Play Store, search for Merge Watch, and install it.Get it on Google Play
  3. Run Merge on your iPhone and keep it foregrounded - the watch scans for it.
  4. On the watch, open Merge and accept the Bluetooth access request.
  5. Your iPhone appears in the device list - tap it to begin pairing.
  6. Confirm the OS-level pairing on both sides.
  7. If prompted, set up your Merge subscription via the iPhone app.
  8. Grant notification and health permissions on both devices when asked.

Samsung's Sleeping Apps feature exists to extend battery life by suspending apps that aren't actively in use - a reasonable goal, but one that conflicts directly with Merge needing to run continuously in the background. The side effect is a dropped connection with no error message. On the watch, go to Settings - Battery - More battery settings - Sleeping apps and remove Merge from the list to keep that from happening.

Day-to-day with iPhone

The 2,000-nit display is the change you notice most in the first week - glancing at a notification outdoors no longer requires repositioning your wrist or cupping your hand. The Exynos W930 with 2GB of RAM keeps the watch responsive under load; no jitter when scrolling through a full notification stack. Via Merge, the complete connection is in place: notifications, calls, music control, contacts, camera remote, and full health sync to Apple Health - all running while AFib monitoring does its own independent work in the background.
